Are you a new Linux user? I suggest you login as root and open the program that enables you to control which services start when the computer is booted. Make sure "pcmcia" is selected. Make sure "network" is selected. Highlight "pcmcia" with your cursor and press on "start". Wait until you get a message indicating "pcmcia" has successfully started. The card LED light may come on. Do the same with "network". If you made any changes, "save" them and exit the "services" program.
Open a "root console" from "System" in the "main menu". At the root prompt which should look something like this [root@localhost@localdomain ~]#, type "dmesg|less". Scroll down using the down page button on your keyboard, or with the cursor on the scroll bar looking for any comment referencing "pcmcia" and your network card. Also, look for any comment regarding drivers being "loaded" or "installed" and their name. If you are in luck, you will see this kind of comment and you may be able to get on the internet with only a few more steps.
At the root prompt, type "lsmod|less" The module or driver name you saw in the "dmesg|less" output should appear as being "loaded" in the "lsmod|less" output.
If not. At the root prompt type "modprobe (and name of your card's driver)" There should be no error message. Type "lsmod|less" again. Do you see the module or driver in the output?
Yes? At the root prompt type "ifcfg wlan0" You should get output related to your card. If the output says "no such file" you probably do not have "wireless tools" installed... If not, come back and we will do some more stuff...
If you do get output related to your card, next at the root prompt type "ifup wlan0" You should not get an error message. At the root prompt type "iwconfig wlan0". There should be output similar to this:
[root@localhost@localdomain ~]# iwconfig wlan0
wlan0 IEEE 802.11b/g ESSID:"Mod Coffeehouse" Nickname:"localhost@localdomain"
Mode:Managed Frequency=2.462 GHz Access Point: 00:11:50:12:AA:9F
